Sig Sauer

Introducing the MCX-REGULATOR, using the heart and soul of the legendary MCX platform combined with a proprietary lower design, all built around shooter ergonomics comes a whole new level of MCX modularity. Never before has a ranch rifle possessed the DNA of a rifle used by elite Special Forces operators around the world.

The MCX-REGULATOR is an aluminum frame rifle with a gas-piston operating system, a Magpul™ SGA Mossberg 500/590 traditional stock combined with a redesigned lower receiver compatible with all MCX upper receivers. It has a fully ambidextrous magazine release, safety selector, and bolt catch. The MCX-REGULATOR ships with a two-stage match trigger, a cold hammer-forged carbon steel barrel, and a SIG-designed muzzle brake. The MCX-REGULATOR offers a built in Arca Rail for easy tripod mounting and ships with a 10-round magazine.
